The standard for Chinese plugs and sockets is set out in GB 2099.1‐2008 and GB 1002‐2008. As part of China's commitment for entry into the WTO, the new CPCS (Compulsory Product Certification System) has been introduced, and compliant Chinese plugs have been awarded the CCC Mark by this system. The plug is two conductor, non-earthed, rated at 10 A, 250 V and used for Class II applications. The Australian plug fits, though the pins on the Chinese plug are thinner and 1 mm (0.039 in) longer. China also uses American/Japanese NEMA 1‐15 sockets and plugs for Class-II appliances. The voltage at a Chinese socket of any type is 220.
